Open Stack

Hi All,

In our OpenStack deployment, API endpoints are defined by using URLs instead of port numbers and HAProxy  forwards requests to the right bakend after having ACLed the URL.

In the case of our object-store service, based on RadosGW, the internal API endpoint is "https://<FQDN>/object-store/swift/v1/AUTH_<tenant_id>"

When Ceilometer RadosGW pollster tries to connect to the RadosGW admin API with the object-store internal endpoint, the URL becomes https://<FQDN>/admin, as shown by HAProxy logs. This URL does not match any API endpoint from HAProxy point of view. The line of code that rewrites the URL is this one: https://opendev.org/openstack/ceilometer/src/branch/stable/wallaby/ceilometer/objectstore/rgw.py#L81

What would you think of adding a mechanism based on new Ceilometer configuration option(s) to control the URL rewriting ?

Our deployment characteristics:
- OpenStack release: Wallaby
- Ceph and RadosGW version: 15.2.16
- deployment tool: OSA 23.2.1 and ceph-ansible


Best regards,
Jean-Francois
